IMPROVEMENT IN GLUE-POTS.

Specification forming part of Letters Patent N 0. 171.922, dated January11, 1876 application filed November 2, 1875.

To all whom it may concern:

Be it known that I, CHARLES S. OoMINs, of the city, county, and State ofNew York, have invented a new and useful Improvement in Glue-Pots; andthat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, making a part of this specification Thisinvention is in the nature of an improvement in glue-pots; and theinvention consists in a glue-pot which is adjustable in its relation toits heating-surface, so that it may be brought nearer to, or fartherfrom, such surface, as cifcumstances may require.

The desirability of keeping the glue, while being used, at the righttemperature. and

avoiding all liability of its boiling over, on the one hand, or becomingchilled on the other, is well known to mechanics who have occasion toprepare and use glue. By my invention this is'accomplished withcertainty and without trouble, as will be seen from the followingdescription and accompanying drawings, wherein is represented alongitudinal section of my improved glue-pot.

A represents the outer shell of a glue-pot, within which is placed thewater, and B the glue-pot proper, which is placed within it, as 111 theordinary construction of glue-pots.

This construction not being novel in any particular, no furtherdescription is needed.

To the center of the under side of the bottom of the shell A is secureda screw, or, which extends downward and at right angles to said bottom.0 represents the base, from which emanates the heat designed to dissolvethe glue. This base has formed through its center an orifice, b. Thisorifice has within it screw-threads corresponding to the threads on thescrew a. The upper surface of the base 0 is closed, as well as its undersurface. The screw 0!, after being entered within the orifice b, may bereceived entirely within said orifice, or but partially so.

Heat belng applied into the base 0 by steam, or in any other desirablemanner, the shell A of the glue-pot is turned so as to send the screw aentirely within the orifice b, which will bring the under surface of theshell closely in contact with the upper surface of the base,

In this position the greatest amount of heat is brought to bear upon theglue-pot, and the glue within it very speedily begins to boil.

Now, to keep the glue, after being properly prepared, at the requisitetemperature, it is.

ting too coolto use.

While the application of this invention, in

the, present instance, is made to a glue-pot, yet it is obvious that theinvention applies equally well to utensils used to prepare food forchildren and invalids, and also to chemical manipulation, and for anyother purpose Where a quick and certain adjustment of temperature may bedesired.

The application of this invention to a glue-pot is particularlydesirable when the heat used is derived from steam. In that case, a pipemay be led into an orifice, as at a, conducting the steam into the base0, and a second pipe may pass from the base 0 at an orifice, as at c,this second pipe leading into the base of a second glue-pot, and so on.A series or chain of glue-pots may be connected with the samesteam-heating apparatus, and yet the whole series of pots may beoperated or used at dif-- ferent degrees of temperature, in like manneras if they were each heated from separate or independent sources.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination of the heater 0, constructed with the threaded orificeb, and the gluepot having the screw it, arranged and operatingsubstantially as described.
